Datepicker to show text when a date is clicked

- Front CMS users must be able to add text/announcements from the CMS panel
- These announcement will be linked to dates on the Datepicker
- When a dates receives an annoucement, the date show in (lets say) yellow
- When the front-user clicks on a date, <div class="annoucements"> slides/shows via jQuery (i can do that... :-))
